Background: Hilar cholangiocarcinoma (HCCA) is a rare tumor, usually associated with obstructive jaundice and unfavorable prognosis. Obstructive jaundice can affect the liver, kidney, heart, and the immune system of the patients. Currently, controversy exists in whether preoperative biliary drainage (PBD) is of any benefit to the patients, and the best way for PBD in patients with resectable HCCA of malignant biliary obstruction remains to be determined.

Aim: To compare the clinical effectiveness of the treatment of choledocholithiasis by laparoscopic common bile duct (CBD) exploration and by endoscopic sphincterotomy (EST).

Materials And Methods: A meta-analysis of studies about CBD stones was performed to analyze EST in comparison with laparoscopic CBD exploration procedures. Trials were identified by searching the Medline, EMBASE, PubMed, CBM, and CNKI databases from January 1990 to December 2012 for laparoscopic CBD exploration or EST for CBD stones.

Article Synopsis
  • The research addresses challenges in treating wastewater from avermectin production, which has high chemical oxygen demand and requires significant dilution for current treatment methods.
  • A yeast strain (H-1) closely related to Candida tropicalis was identified for its ability to thrive in avermectin-rich wastewater, demonstrating substantial growth, with a 66.67% reduction in COD and 99.48% removal of avermectins under optimal conditions.
  • The resulting dry yeast powder, with high protein content and low moisture, shows potential as a valuable and cost-effective resource for further avermectin production.

Aim: To evaluate survival and recurrence after radiofrequency ablation (RFA) for the treatment of small hepatocellular carcinoma (HCC) using a meta-analysis.

Methods: Literature on RFA vs surgical resection for the treatment of small HCC published between January 1990 and December 2008 was retrieved. A meta-analysis was conducted to estimate pooled survival and recurrence ratios.

Nattokinase is a novel fibrinolytic enzyme that is considered to be a promising agent for thrombosis therapy. In this study, reverse micelles extraction was applied to purify and concentrate nattokinase from fermentation broth. The effects of temperature and phase volume ratio used for the forward and backward extraction on the extraction process were examined.
